World Ocean Database 2009

World Ocean Database 2009 (WOD09) is a collection of scientifically quality-controlled ocean profile and plankton data that includes measurements of temperature, salinity, oxygen, phosphate, nitrate, silicate, chlorophyll, alkalinity, pH, pCO2, TCO2, Tritium, delta-13Carbon, delta-14Carbon, delta-18Oxygen, Freons, Helium, delta-3Helium, Neon, and plankton. A discussion of data sources is provided. Data are both historical and modern with the most recent data from 2008.World Ocean Database 2009 is an update of World Ocean Database 2005. It expands on the older version by including new variables, data types, and additional historical, as well as modern, observations. It contains all data from earliest observation through our collection as of Dec. 31, 2009. The 2009 database, updated from the 2005 edition, is significantly larger providing approximately 9.1 million temperature profiles and 3.5 million salinity reports. The 2009 database also captures 29 categories of scientific information from the oceans, including oxygen levels and chemical tracers, plus information on gases and isotopes that can be used to trace the movement of ocean currents. An online version of the World Ocean Database is updated quarterly. This subset of the World Ocean Database contains the biological observations only.2009年世界海洋数据库（World Ocean Database 2009，WOD09）是一套经过科学质量管控的海洋剖面与浮游生物数据集，涵盖温度、盐度、溶解氧、磷酸盐、硝酸盐、硅酸盐、叶绿素、碱度、pH值、二氧化碳分压（pCO2）、总二氧化碳（TCO2）、氚、碳-13同位素比值（δ¹³C）、碳-14同位素比值（δ¹⁴C）、氧-18同位素比值（δ¹⁸O）、氟利昂、氦、氦-3同位素比值（δ³He）、氖以及浮游生物的实测数据。文中提供了该数据集数据来源的详细说明。该数据集涵盖历史与现代海洋观测数据，最新观测数据采集于2008年。2009年世界海洋数据库是2005年世界海洋数据库的更新版本，相较于旧版数据库，本数据集新增了观测变量与数据类型，并补充了更多历史及现代海洋观测记录。其收录了自最早海洋观测记录起至2009年12月31日收集的全部海洋观测数据。相较于2005版，2009版数据库规模显著扩大，包含约910万条温度剖面数据与350万条盐度实测报告。2009版数据库还收录了海洋领域29类科学信息，包括溶解氧水平与化学示踪剂数据，以及可用于追踪洋流运动的气体与同位素相关资料。世界海洋数据库的在线版本每季度更新一次。本次发布的该数据库子集仅包含生物观测数据。
